摘要：

使用GC-MS测定兰炭废水中有机物的成分及含量, 然后用兰炭废水中最具代表性的 5 种酚类物质(苯酚、间甲酚、2,3-二甲基苯酚、邻苯二酚和2,6-二甲基苯酚)组成的单酚或混合酚模拟兰炭废水, 在甲醛存在条件下制备酚醛树脂。通过对制备的酚醛树脂进行原位红外表征及热分析表征检测, 从热重分析数据获得热解动力学参数。结果表明, 混合酚的交联度更高, 酚醛树脂更稳定。研究结果可为优化甲醛法处理兰炭废水提供理论依据。

Abstract:

The composition and concentration of organic compounds in semi-coking wastewater were determined by GC-MS. The mixtures of a few of the five most representative phenolic substances (phenol, m-cresol, 2,3-dimethylphenol, catechol and 2,6-dimethylphenol) were utilized to simulate semi-coking wastewater. Phenolic resins in the simulated semi-coking wastewater were prepared in the presence of formaldehyde. The phenolic resins were characterized by in-situ infrared and thermal analysis. The pyrolysis kinetic parameters obtained from analyzing thermogravimetric analysis data indicated that a mixture of phenolic compounds had higher crosslinking degree and the phenolic resin was more stable. This study provides a theoretical basis for optimizing of semicoking wastewater treatment by utilizing formaldehyde.

Key words: semi-coking water, phenolic compounds, phenolic resins, pyrolysis kinetics
